Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and specifically to a combined electrical transformer. Background Art

[0002] In today's power systems, combined electrical transformers are widely used in various scenarios, from the power distribution networks in bustling cities to the power supply facilities in remote areas. However, a significant portion of traditional combined electrical transformers have notable design flaws, and their external structures cannot effectively protect against collisions. In industrial production areas, large mechanical equipment operates frequently, and transport vehicles shuttle back and forth. Transformers are often damaged due to accidental mechanical collisions. For example, during the process of forklift carrying goods, it may directly hit the transformer due to operational errors. Due to the lack of external protection, the transformer shell can easily be dented or cracked, leading to the displacement or damage of core components such as internal windings and iron cores, causing serious power failures, affecting the normal operation of the entire production line, and bringing huge economic losses.

[0003] In urban streets and communities, with the continuous progress of urban construction and renovation projects, it is inevitable that construction machinery will approach transformers when operating in narrow spaces. During construction, small excavators, loaders and other equipment, once they touch the transformer, the transformer without a protective structure cannot withstand such an impact. The internal electrical connections may be broken, and the insulating materials may also be cracked due to the collision. This not only leads to the interruption of power supply, but also may cause safety hazards such as electric leakage, posing a serious threat to the lives and property safety of surrounding residents. Even in the relatively stable outdoor substation environment, it is not completely safe. Strong winds may blow down surrounding trees and hit the transformer, and accidental collisions also occur frequently when small animals move near the transformer. Without protection, transformers are extremely vulnerable to serious damage under these seemingly accidental collisions. Frequent fault repairs not only consume a large amount of human and material resources, but also pose a great challenge to the stability of the entire power grid.

[0004] Therefore, it is very necessary to design a combined electrical transformer with strong practicability. Summary of the Invention

[0005] The purpose of the present invention is to provide a combined electrical transformer to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A combined electrical transformer, comprising:

[0007] A transformer body;

[0008] A shock-absorbing assembly for damping the vibration generated during the operation of the transformer body, and the shock-absorbing assembly is installed on the bottom surface of the transformer body;

[0009] A protection component is provided outside the transformer body and is used to protect the outside of the transformer body. The protection component is connected to a shock absorption component.

[0010] A heat dissipation component is installed outside the transformer body and is used to dissipate heat during the operation of the transformer body.

[0011] According to the above technical solution, the shock absorption component includes:

[0012] A mounting plate, the top surface of which is fixedly installed with the bottom surface of the transformer body;

[0013] A shock pad, the top surface of which is fixedly installed with the bottom surface of the mounting plate. The bottom surface of the shock pad is fixedly installed with an L-shaped bottom plate.

[0014] According to the above technical solution, the shock absorption component further includes:

[0015] A mounting block, which is fixedly installed on the bottom surface of the L-shaped bottom plate;

[0016] A movable rod, one end of which is movably connected to the mounting block through a pin. The end of the movable rod far from the mounting block is movably connected to a slider. The lower end of the slider is slidably arranged in a guide rail groove formed on the surface of the L-shaped bottom plate;

[0017] A cylindrical rod, which is slidably sleeved with the slider. The end of the cylindrical rod is fixedly installed with a fixing plate, and the bottom surface of the fixing plate is fixedly installed with the L-shaped bottom plate;

[0018] A shock absorption spring, which is sleeved outside the cylindrical rod. One end of the shock absorption spring is fixedly installed with one surface of the slider, and the end of the shock absorption spring far from the slider is fixedly installed with one surface of the fixing plate.

[0019] According to the above technical solution, the protection component includes:

[0020] An L-shaped connecting plate, the end of which is fixedly installed with the L-shaped bottom plate;

[0021] A protection side plate, the lower end of which is located in a rectangular groove formed on the top surface of the L-shaped connecting plate and is slidably arranged in the rectangular groove;

[0022] A sliding column, both ends of which are slidably arranged in a sliding groove formed on the inner wall of the rectangular groove;

[0023] A first buffer spring, which is sleeved outside the sliding column. One end of the first buffer spring is fixedly installed with one surface of the protection side plate, and the end of the first buffer spring far from the protection side plate is fixedly installed with the inner wall of the rectangular groove.

[0024] According to the above technical solution, a protective fence is fixedly installed on one side of the protective side plate. The number of the protective fences is multiple, and the multiple protective fences are equally spaced. The arranged protective fences can protect the front and rear positions of the transformer body.

[0025] According to the above technical solution, there is a distance between the side of the protective side plate close to the transformer body and the inner wall of the rectangular groove. Such a setting can enable the protective side plate to have a movement range during a collision, thereby assisting in the buffering effect.

[0026] According to the above technical solution, the outer diameter of the sliding column is smaller than the length of the inner wall of the sliding groove. A second buffer spring is arranged in the sliding groove. One end of the second buffer spring is fixedly installed on the outer wall of the sliding column, and the end of the second buffer spring far from the sliding column is fixedly installed on the inner wall of the sliding groove. This can enable the sliding column to have an activity range in the sliding groove and assist in the buffering effect.

[0027] According to the above technical solution, the heat dissipation component includes:

[0028] A heat absorption tube, which is U-shaped, and both ends of the heat absorption tube are fixedly installed on the surface of the transformer body;

[0029] A heat conduction tube, which is sleeved outside the heat absorption tube;

[0030] A heat dissipation connecting piece, which is fixedly installed on the bottom surface of the heat conduction tube;

[0031] A front heat dissipation fin and a rear heat dissipation fin, which are arranged in the front and rear positions and are both fixedly installed on the heat dissipation connecting piece.

[0032] According to the above technical solution, the number of the front heat dissipation fins and the rear heat dissipation fins is the same, and they are made of the same material. The multiple front heat dissipation fins and rear heat dissipation fins are equally spaced.

[0033] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0034] 1. In the present invention, when the transformer body vibrates, the shock-absorbing pad plays a basic shock-absorbing role to reduce the vibration amplitude. At the same time, when the angle of the movable rod below the mounting plate changes, it pushes the slider to slide on the guide rail groove and the cylindrical rod, driving the shock-absorbing spring to cooperate in shock absorption. The multiple shock-absorbing mechanisms cooperate to greatly reduce the vibration amplitude and effectively protect the transformer body.

[0035] 2. In the present invention, when the outside of the transformer body is collided by an external object, the protective side plate and the protective fence can directly block the collision and prevent the body from being damaged. When the protective side plate is collided in the lateral or front-rear direction, it respectively causes the first buffer spring and the second buffer spring to produce a buffering effect, reducing the damage force caused by the collision and protecting the transformer in all directions.

[0036] 3. In the present invention, a large amount of heat is generated during the continuous operation of the transformer. The heat absorption tube is responsible for absorbing the heat, and the heat conduction tube conducts the heat on the surface of the heat absorption tube. Through the heat dissipation connecting piece, the front heat sink and the rear heat sink, efficient heat dissipation is achieved, preventing the internal structure of the transformer from being damaged due to high temperature and ensuring the stable operation of the equipment.

[0052] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0053] Please refer to Figures 1-8 , the present invention provides a technical solution: a combined electrical transformer, characterized in that it includes:

[0054] Transformer body 1.

[0055] Embodiment 1: Refer to Figure 3 , the shock absorption component 2, which is used to reduce the vibration generated during the operation of the transformer body 1 and play a shock absorption role. The shock absorption component 2 is installed on the bottom surface of the transformer body 1.

[0056] Specifically, the shock absorption component 2 includes:

[0057] The mounting plate 21, the top surface of which is fixedly installed with the bottom surface of the transformer body 1;

[0058] The shock absorption pad 23, the top surface of which is fixedly installed with the bottom surface of the mounting plate 21, and the bottom surface of the shock absorption pad 23 is fixedly installed with an L-shaped bottom plate 22.

[0059] Here, the provided shock absorption pad 23 can effectively reduce the vibration when the transformer body 1 vibrates and play a protective role for the transformer body 1.

[0060] In this embodiment, the shock absorption component 2 further includes:

[0061] The mounting block 24, which is fixedly installed on the bottom surface of the L-shaped bottom plate 22;

[0062] The movable rod 25, one end of which is movably connected to the mounting block 24 through a pin. The end of the movable rod 25 far from the mounting block 24 is movably connected to a slider 26, and the lower end of the slider 26 is slidably arranged in the guide rail groove 5 opened on the surface of the L-shaped bottom plate 22;

[0063] The columnar rod 27 is slidably sleeved with the slider 26, and a fixing plate 29 is fixedly installed at the end of the columnar rod 27, and the bottom surface of the fixing plate 29 is fixedly installed with the L-shaped bottom plate 22;

[0064] The shock absorbing spring 28 is sleeved on the outside of the columnar rod 27 , one end of the shock absorbing spring 28 is fixedly mounted on one side of the slider 26 , and one end of the shock absorbing spring 28 away from the slider 26 is fixedly mounted on one side of the fixing plate 29 .

[0065] Here, when the transformer body 1 vibrates, the movable rod 25 will move and drive the slider 26 to move, so that the shock absorbing spring 28 plays a shock absorbing role.

[0066] Example 2: Reference Figure 4 , Figure 5 and Figure 6 The protective component 3 is arranged outside the transformer body 1 and is used to protect the outside of the transformer body 1. The protective component 3 is connected to the shock absorbing component 2.

[0067] Specifically, the protection component 3 includes:

[0068] An L-shaped connecting plate 31, the end of which is fixedly mounted to the L-shaped bottom plate 22;

[0069] The lower end of the protective side plate 32 is located in the rectangular groove 6 opened on the top surface of the L-shaped connecting plate 31, and is slidably arranged with the rectangular groove 6. A distance is set between the side of the protective side plate 32 close to the transformer body 1 and the inner wall of the rectangular groove 6. This arrangement allows the protective side plate 32 to have a moving range when colliding, thereby playing an auxiliary role in the buffering effect;

[0070] The sliding column 34 is slidably arranged with the sliding groove 7 opened on the inner wall of the rectangular groove 6 at both ends. The outer diameter of the sliding column 34 is smaller than the length of the inner wall of the sliding groove 7. A second buffer spring 36 is arranged in the sliding groove 7. One end of the second buffer spring 36 is fixedly installed with the outer wall of the sliding column 34, and the end of the second buffer spring 36 away from the sliding column 34 is fixedly installed with the inner wall of the sliding groove 7. In this way, the sliding column 34 has a range of movement in the sliding groove 7, which can play an auxiliary role in the buffering effect.

[0071] The first buffer spring 35 is sleeved on the outside of the sliding column 34 , one end of the first buffer spring 35 is fixedly installed on one side of the protective side plate 32 , and one end of the first buffer spring 35 away from the protective side plate 32 is fixedly installed on the inner wall of the rectangular groove 6 .

[0072] Here, the protective side plate 32 can protect the side of the transformer 1, and the first buffer spring 35 and the second buffer spring 36 can buffer the protective layer plate 32 when it collides, thereby enhancing the protective effect.

[0073] In this embodiment, a protective fence 33 is fixedly installed on one side of the protective side plate 32. The number of the protective fences 33 is multiple, and the multiple protective fences 33 are evenly distributed at equal intervals. The arranged protective fences 33 can play a protective role in the front and rear positions of the transformer body 1.

[0074] Embodiment 3: Refer to Figure 7 and Figure 8 , a heat dissipation component 4, is installed outside the transformer body 1 and is used for dissipating heat during the operation of the transformer body 1.

[0075] Specifically, the heat dissipation component 4 includes:

[0076] A heat absorption tube 41, which is U-shaped, and both ends of the heat absorption tube 41 are fixedly installed on the surface of the transformer body 1;

[0077] A heat conduction tube 42, which is sleeved outside the heat absorption tube 41;

[0078] A heat dissipation connection piece 43, which is fixedly installed on the bottom surface of the heat conduction tube 42;

[0079] A front heat dissipation fin 44 and a rear heat dissipation fin 45 are arranged in the front and rear positions and are both fixedly installed with the heat dissipation connection piece 44.

[0080] Here, through the arranged heat absorption tube 41, heat conduction tube 42, heat dissipation connection piece 43, and the arranged front heat dissipation fin 44 and rear heat dissipation fin 45, an effective heat dissipation effect can be achieved during the operation of the transformer body 1, and the transformer body 1 can be prevented from being damaged due to high temperature.

[0081] In this embodiment, the number of the front heat dissipation fins 44 and the rear heat dissipation fins 45 is the same, and the same material is used. The multiple front heat dissipation fins 44 and rear heat dissipation fins 45 are evenly distributed and installed at equal intervals.

[0082] Working principle: When the transformer body 1 vibrates, at this time, the shock pad 23 will produce a shock-absorbing effect, reducing the vibration amplitude. At the same time, the movable rod 25 installed below the mounting plate 21 will undergo an angular movement change. By using this change, the slider 26 can be pushed to slide on the guide rail groove 5 and the cylindrical rod 27, thereby driving the shock-absorbing spring 28 to absorb shock. Cooperating with the shock pad 23, the vibration amplitude is greatly reduced, playing a protective role for the transformer body 1; when the outside of the transformer body 1 is collided by an external object, first of all, the protective side plate 32 and the protective fence 33 provided can play a protective role for the transformer body 1, avoiding damage to the transformer body 1. Here, when the protective side plate 32 is collided laterally, the protective side plate 32 will move laterally, causing the first buffer spring 36 to produce a buffering effect and reducing the damage force. When the protective side plate 32 is collided front and back, the protective side plate 32 can move back and forth, causing the second buffer spring 36 to produce a buffering effect and reducing the damage force; here, during the continuous operation of the transformer body 1, a large amount of heat will be generated inside. At this time, the heat is absorbed by the heat absorption tube 41 provided, and then the heat on the surface of the heat absorption tube 41 can be exported through the heat conduction tube 41 provided. Finally, with the setting of the heat dissipation connecting piece 43, the front heat sink 44 and the rear heat sink 45, the heat dissipation purpose can be achieved, avoiding damage to the internal structure of the transformer body 1 due to high temperature.
